STEELDIVE SD1972 6105-8110 King Turtle Dive Watch V2

product link： Overview The SD1972 is a homage to the Seiko "King Turtle" which was a premium version of the Seiko 6309 "Turtle" which is often confused with the Seiko 6105 "Willard". However,the 6309 had a much more utilitarian look and also a slightly bigger dial with different markings and a bigger lug width. The "King Turtle" was then given Day/Date with a magnifier and was generally more refined but was then put at a higher price point so it could be potentially worn as a dress watch without offending all your guests at your exclusive dinner party in Mayfair.
